Sarai Dashboard, revisited
This dashboard runs full-screen at 1280x1024 on a 19" monitor connected to my iMac, being served by the Sarai hub sitting over by my television. Incoming information from RSS feeds or Breaking News are automatically sent to my main iMac display as Growl notifications thanks to Fluid's Growl. It's a single-serving site in a single-serving browser, almost completely done in JS (my analogue clocks are done in Flash simply for the sake of fluidity — the canvas element redraw is still a little slow.)
Note: This is a mockup, but the code is almost done and operational.
Also note: I originally went white-on-black for a power consumption reason, but according to Titanas (in the comments below) this is a myth. Thanks for clearing that up. I probably would have done something far less modernist.
